AI-Powered Test Revolutionizes Early Breast Cancer Detection. A groundbreaking test using laser technology and artificial intelligence can now detect breast cancer at its earliest stage, 1a, according to researchers from the University of Edinburgh, Sky News reports. The non-invasive method identifies subtle changes in the bloodstream undetectable by existing diagnostic tools, offering a significant advancement in early detection. The test works by shining a laser beam into blood plasma samples, which are then analyzed to reveal chemical changes in cells and tissues linked to early-stage cancer. AI interprets the results with remarkable precision, achieving 98% accuracy in identifying stage 1a breast cancer during a pilot study of 24 samples. The test can also distinguish between the four main subtypes of breast cancer with over 90% accuracy, paving the way for more personalized and effective treatments. The breakthrough technology could improve survival rates by enabling earlier diagnoses, addressing a critical challenge in cancer care where late-stage detection is common. Dr. Andy Downes, who led the study, emphasized the potential for the method to expand beyond breast cancer to become a multi-cancer screening tool. The technique builds on the success of laser-based diagnostics in other cancers, such as bowel cancer, but this is the first application targeting early detection. Current breast cancer screenings rely on physical exams, imaging, or biopsies, but this new method could enhance early detection even for those outside at-risk groups. Researchers hope to refine the test further and create a database to apply the technology to other cancer types, potentially transforming cancer diagnostics.
